Abstract

The opportunities associated with the global supply chain of rolling element bearings has OEM sourcing specialists and design engineers searching for the best practice to evaluate and qualify new bearing suppliers. Historical qualification procedures involving only field testing have given way to the addition of bearing inspection and a variety of lab tests to reduce qualification lead times, acceptance cost and product risk, but there is still an additional step. The incorporation of a basic stress analysis after bearing inspection and before product testing can provide quick and low cost information to determine the net effect that manufacturing design and quality of workmanship have on contact stress. A basic analysis can be performed without complex modeling allowing the design engineer to determine if further dynamic testing is justifiable. This webinar will review the inspection characteristics needed to conduct a basic stress analysis. We’ll then look at raceway and roller contact stress under different operating conditions and determine the influence that design or manufacturing quality have on contact stress. A stress analysis at this step can lead to supplier discussions about improved design and manufacturing quality, offsetting poor performance during dynamic life test validation.

Speaker Biographies

Chris Napoleon founded Napoleon Engineering Services in 1997, after several years in the aerospace bearing industry, with a clear vision and passion for increasing bearing knowledge and performance throughout all industries. With the increase in the global supply chain for bearings Chris saw a need for companies to reduce risk when sourcing product and developed our Inspection and Testing departments. Today, under Chris’ guidance, NES has become the largest independent bearing testing and inspection facility in the United States.

Chris has devoted the past 16 years of his career to providing bearing qualification solutions to design engineers and corporate supply planners through extensive and unique forms of bearing testing and inspection. The programs he has developed have helped hundreds of large OEMs make informed decisions about the global supply chain and improved bearing performance in their applications.

The highlight of Napoleon Engineering Services inspection program is the Source Qualification Inspection (SQI) program, a unique service which provides a comparison between multiple bearing suppliers. Chris has developed this program which determines the design intentions, manufacturing quality, material integrity, and overall quality of workmanship, opening the world of bearing design for non-bearing engineers.

Napoleon Engineering Services has seen outstanding growth in its 16 years of development under Chris, with the company recently settling into its state of the art 20,000 sq ft facility which was completed at the beginning of the year. Under Chris’ direction and leadership Napoleon Engineering Services continues to strive in all three aspects of the business; Bearing Inspection, Bearing Testing, and Custom Bearing Manufacturing and looks forward to future growth in the years to come.

Colby Austin A graduate Mechanical Engineer, Colby has worked within NES' bearing testing department as a design engineer, bearing engineer and now as the technical business manager for bearing inspection and bearing testing. He has a developed a keen understanding of the importance of identifying the customer's need for testing and developing an inspection and test plan to satisfy that need. He has been instrumental in the development of statistical techniques to evaluate bearing test results and is instrumental is the design of custom bearing test rigs for both NES and customer use.
